Gastric Banding

Just south of Miami, Tom, a gastric bypass doctor, was talking with Sally.  Sally may want gastric banding.  Gastric banding, Tom said, is not for small boys or girls. This is odd, Sally said. It is not doctor Tom’s information, but this paragraph that is odd.

How quickly can you find out what is unusual about this paragraph, too?  It looks so ordinary that you would think that nothing is wrong with it at all-- and, in fact, nothing is.  But it is a bit odd and possibly awkward. Why?  If you study it and think about it, you may find out.
